Well, if it really had a motherboard hardware problem, then it seems unlikely that its failure had anything to do with your installation of ubuntu. My suggestion would be to boot into ubuntu via a livecd or a liveusb. This way you can see how ubuntu works without actually going through the full install. You will be able to see if are any hardware compatibility issues and such. It will boot slower and may run slower from CD/USB than a harddrive install will, but it will give you an idea of what a full install will look like.

Also, are you sure you should use a 64bit version? 32bit works on 64s but not vice versa (as far as I know...)
